The raison d'être of meiosis is shuffling of genetic information via Mendelian segregation
and, within individual chromosomes, by DNA crossing-over. These outcomes are enabled …

A large and significant portion of eukaryotic transcriptomes consists of noncoding RNAs
(ncRNAs) that have minimal or no protein-coding capacity but are functional. Diverse …

INTRODUCTION Epigenetic modifications to chromatin, such as the methylation of DNA
cytosines, carry regulatory information across the generations in plants and animals …

In higher plants, male meiosis is a key process during microsporogenesis and is crucial for
male fertility and seed set. Meiosis involves a highly dynamic organization of chromosomes …

Small RNAs are abundant in plant reproductive tissues, especially 24-nucleotide (nt) small
interfering RNAs (siRNAs). Most 24-nt siRNAs are dependent on RNA Pol IV and RNA …

Abstract In Arabidopsis (Arabidopsis thaliana), DNA-dependent RNA polymerase IV (Pol IV)
is required for the formation of transposable element (TE)-derived small RNA transcripts …

Meiotic recombination requires the specific RecA homolog DMC1 recombinase to stabilize
strand exchange intermediates in most eukaryotes. Normal DMC1 levels are crucial for its …

Callose is a plant cell wall polysaccharide whose deposition is spatiotemporally regulated in
various developmental processes and environmental stress responses. The appearance of …

Background Neo-tetraploid rice lines exhibit high fertility and strong heterosis and harbor
novel specific alleles, which are useful germplasm for polyploid rice breeding. However, the …

Fluorescence in situ hybridization (FISH) is an indispensable technique for studying
chromosomes in plants. However, traditional FISH methods, such as BAC, rDNA, tandem …
